sPno'I-FIATIGN forming perf of Lettere Patent No. 636,852, cie/eea November 14, 1899. Application filed August 1, 1898. Serial No. 687,384. (No model.)

2 is an end elevation and partial section of the same at line 2 2 of Fig. 1, looking from left to right of said figure Fig. 3 is a crosssection at line 3 3 of Fig. 1, looking from left to right; and Fig. 4 is an end elevation and partial section at line 4 4 of Fig. 1; looking from right to left vof said figure.

In the drawings,5 represents a suitable base,-

on which the apparatus is mounted; A, a sheet-metal cylinder having circumferential rings 6 and 7 riding, respectively, upon Jn he carrying-rolls 8 and 9, which rolls are preferably grouped in pairs, as illustrated in Fig. 3, and are mounted in yokes 10, which swing on pivots 11. The rolls 9 have flanges 12 to hold the cylinder from longitudinal displacement. The cylinder is also provided with a gear-.ring 13, with which meshes a pinion 1'4, carried by a shaft 15, having a belt-drum`16 or other suitable means of receiving and conveying power. The front or left-hand end of the cylinderAis open for nearly its entire diameter and extends into the drum 17, into the head of which drum enters a chute 18 for the delivery of the material, the chute extending downwardly and inwardly, so as to deposit the same within the cylinder A, as shown in Fig. 1. The flap 19 coversa peep-hole which permits a view of the interior of the cylinder when in use. The pipe or stack 2O serves as an outlet and may be connected with a blower or chimney or other meansfor producing any desired draft. The other end of the cylinder opens into a drum 2l, at the bottom of which is a delivery-chute 22 for the material as it passes from the machine.

FiXed within the cylinder-A is a sheet-metal iue B, preferably pear-shaped in crosssection or with its upper portion of inverted- V shape. This lue is supported in any suitable manner, as by means of hangers 23, theend of the flue extending, preferably, into the drum 21 and the relative operations of the cylinder and flue being such that the cylinder will serve as a return-Hue for heated gases and lead them to stack 20. Connected with the other end of the flue is a pipe 24, preferably with a refractory lining 25, which pipe extends to a furnace or other source of heat. Arranged upon the inclined surface of the iiue B are the series of angle-iron bars ordeiiectors 26,-the lower ends of which are pivoted to the flue and the upper ends to an operating-bar 27. This bar extends from the drum `21 and is fitted with 'an operating-lever 28, by means of which the angular position of the deiiectors 26 may be adjusted for the purposes hereinafter described,the operatingbar working in notches in the bars 26a.

Arranged upon the inner surface of the cylinder A is a series of buckets or angular steps which serve as the cylinder is rotated to carry the material deposited in it upward and to drop it upon the top of the flue B, down the inclined surface of which it slides and is forwardly delivered by the deiiectors, the degree of forwarding the delivery of the material being determined by the angle at which the deflectors are set, the object of this varrangement being to adjust the apparatus according to the condition of the material. It' very wet, the deiiectors are set at a high angle, so as to cause the material to be pushed slowly through the machine, and therefore thoroughly dried, whereas if the material is in less moist condition the delectors can be set at a greater angle and the material carried through more rapidly.

Access to the interior of the cylinder is given bythe door 30 for the purpose of repair or cleaning. v

The operation of the apparatus is readily understood from the drawings and foregoing description, the heated gases being delivered from a furnace through the pipe 24 into the apparatus, and the cylinder A being rotated the sand or other material is delivered into the chute 18 upon the bottom of the cylinder AZ Thus by the rotation of the cylinder this is carried by the buckets upward and dropped IOO down the chute to the ilue B. The delectors carry it step by step forward with each operation, and the parts being properly adjusted when the material has just been conveyed to the other end of the apparatus, which has been thoroughly dried for the purposes desired, and is delivered from the cylinder through the chute 22, products of combustion, not only heating the materials as they pass from the Hue, but also as they return outside the flue and within the cylinder to the stack 20, come in contact with the material and serve to dry the same.

I claim- I. In a drier, in combination, a stationary, open-end iiue, a rotatable inelosing cylinder serving as a return-nue, means upon the cylinder for elevating and depositing the material upon the stationary flue, and adjustable means upon the latter for conveying said material forward in said cylinder as it drops from said flue.

2. In a drier, the combination with a rotatable cylinder, having interiorly-arranged buckets, of a stationary flue arranged therein having its top of inverted-V shape in crosssection and provided with a series of ribs or defiectors adjustable upon said V-shaped surface, as and for the purposes specified.

3. In combination, a revoluble cylinder, an

axially-arranged im perforate fixed flue therein connected with a source of heat, said cylinder and flue being interspaeed sufficiently to permit the iiow of material under treatment therethrough and to serve as aq returniiue for the heated gases, circumferentiallyarranged elevating means upon the interior of the cylinder,and adjustable longitudinally conveying means upon the said flue, substantially as and for the purposes specified.

4. In a drier, the combination of the horizontal rotatable cylinder, one end communieating with a discharge-chiite, and the other with an inlet-chute and a gas-outlet, an open# end lue connected with a source of heat, and so arranged in said cylinder that the latter serves as a carrier for the material to be dried and a return-Hue for the heating-gases, the buckets upon the interior of the cylinder for' elevating the material and dropping it upon the iiue, the forwardly-inclined delectors pivoted to the flue and the shifting rod for adjusting the angle of the deiiectors.
